function varargout = Traffic_Iden(varargin)
% TRAFFIC_IDEN MATLAB code for Traffic_Iden.fig
%      TRAFFIC_IDEN, by itself, creates a new TRAFFIC_IDEN or raises the existing
%      singleton*.
%
%      H = TRAFFIC_IDEN returns the handle to a new TRAFFIC_IDEN or the handle to
%      the existing singleton*.
%
%      TRAFFIC_IDEN('CALLBACK',hObject,eventData,handles,...) calls the local
%      function named CALLBACK in TRAFFIC_IDEN.M with the given input arguments.
%
%      TRAFFIC_IDEN('Property','Value',...) creates a new TRAFFIC_IDEN or raises the
%      existing singleton*.  Starting from the left, property value pairs are
%      applied to the GUI before Traffic_Iden_OpeningFcn gets called.  An
%      unrecognized property name or invalid value makes property application
%      stop.  All inputs are passed to Traffic_Iden_OpeningFcn via varargin.
%
%      *See GUI Options on GUIDE's Tools menu.  Choose "GUI allows only one
%      instance to run (singleton)".
